Re: alluminum flywheel?
As has been mentioned a light weight aluminum flywheel may or may not cause transmission rattle, but likely will. Mine has moderate to loud rattle. One thing that can be done to mitigate the rattle is a countershaft shim kit that is very easy to install with the trans out of the car. Carolina Clutch provides such a Kit. It will be my next winter project.

Re: alluminum flywheel?
Thanks, Hans! I never heard of this shim kit,
or that this might help with the rattle. Anybody have any experience with the kit? Does it help? Ted

This is the exact same thing Bill B does when he rebuilds a trans and sets it up for an aluminum flywheel to minimize rattle. H

Re: alluminum flywheel?
This may not be apples to apples comparison.. but I had an 89 mini ram car before the ZR-1. It had a centerforce steel single mass flywheel, weighed close to the dual mass, car was fun to drive. I installed a fidanza aluminum one. I hated driving the car after that. Was more of a chore than fun to drive on the street. My 1990 ZR-1 has exhaust, headers and 4.10s with stock flywheel. I love driving it. Since you are having the work done I agree with Ted and Zman, port and chip it.

Sorry. If I had to do that again, I'd just use the MSDs.

Should be here soon! The coil's on my car are the one's that came with it and I want a hotter ignition system and a wider gap on my plugs.
